DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Referring to Figures 1-7 An embodiment provided by the utility model:

[0030] A vertical machining center convenient to position, including processing body 1, the inside of processing body 1 front end is provided with cleaning mechanism 2, cleaning mechanism 2 includes protective door 201, the inside lower end of protective door 201 is fixedly provided with motor 203, the output end of motor 203 is fixedly provided with reciprocating screw rod 206, reciprocating screw rod 206 is externally threadedly connected with mounting plate 204, push rod 202 is slidably arranged in one side of the inside of mounting plate 204, fixed plate 205 is clamped to one side of mounting plate 204, cleaning block 211 is fixedly arranged in the front end of fixed plate 205, rotating block 209 is rotatably arranged in the upper and lower ends of one side of push rod 202, clamping block 208 is rotatably arranged in the opposite side of the two rotating blocks 209, the opposite side of the two clamping blocks 208 is clamped to the inside of fixed plate 205, compression spring 210 is fixedly arranged in the side of push rod 202 away from motor 203, one side of compression spring 210 is fixedly arranged in the inside of mounting plate 204 close to motor 203, guide rod 207 is fixedly arranged in the inside of protective door 201 away from motor 203, mounting plate 204 is slidably arranged in the outside of guide rod 207, and cleaning block 211 is slidably arranged in the rear end of protective door 201;

[0031] Specifically, during processing, when the observation window at the upper end of the protective door 201 is blocked by the splashing of cooling water on the observation window, the motor 203 inside the protective door 201 can be started to drive the reciprocating screw rod 206 at the output end to rotate. The rotation of the reciprocating screw rod 206 will cause the mounting plate 204 to move reciprocally along the guide rod 207, thereby causing the cleaning block 211 to automatically wipe the observation window, restoring a clear view. This process does not require manual intervention, ensuring that the operator can continuously monitor the processing state, improving the safety and efficiency of operation, and avoiding operational errors or safety accidents caused by blocked vision. When replacing the cleaning block 211, the push rod 202 is simply pressed to slide the push rod 202 inside the mounting plate 204. The sliding of the push rod 202 will pull the compression spring 210 connected thereto, causing it to deform inside the mounting plate 204. The push rod 202 will rotate the rotating block 209 while moving, thereby causing the clamping block 208 to move towards each other inside the mounting plate 204, causing the clamping block 208 to gradually loosen the locking of the fixed plate 205. When the clamping block 208 completely separates from the inside of the fixed plate 205, the fixed plate 205 can be slid out, thereby realizing quick replacement of the cleaning block 211. The entire replacement process is simple and fast, without the need for complex tools and steps, reducing maintenance costs and time.

[0032] Referring to Figures 1-4 The lower end of the processing body 1 is provided with a clamping mechanism 5. The clamping mechanism 5 includes a bottom plate 501, a double-action air cylinder 507 fixedly arranged at the lower end inside the bottom plate 501, a moving block 506 fixedly arranged at the output end of the double-action air cylinder 507, a connecting block 508 rotatably arranged at both sides of the two moving blocks 506, a sliding block 502 slidingly arranged inside the bottom plate 501, a screw rod 505 threadedly connected to the inside of the sliding block 502 away from the double-action air cylinder 507, a clamping plate 503 rotatably arranged at the opposite side of the two screw rods 505, a connecting block 508 rotatably arranged at the front and rear ends of the two sliding blocks 502, a second fixed rod 509 fixedly arranged at the side of the bottom plate 501 close to the double-action air cylinder 507, a sliding block 502 slidingly arranged at the outside of the two second fixed rods 509, a first fixed rod 504 fixedly arranged at the opposite side of the two clamping plates 503, and a first fixed rod 504 slidingly arranged at the inside of the two sliding blocks 502. The lower end of the bottom plate 501 is arranged at the upper end of the electric sliding rail 6, and the lower end of the electric sliding rail 6 is fixedly arranged at the lower end inside the processing body 1. A hydraulic cylinder 4 is fixedly arranged at the upper end inside the processing body 1, and a processing knife 3 is fixedly arranged at the output end of the hydraulic cylinder 4.

[0033] Specifically, when preparing for processing, first place the workpiece to be processed on the bottom plate 501, at this time, activate the two-way air cylinder 507, so that its output end drives the moving block 506 to extend, with the sliding of the moving block 506, the connecting blocks 508 on both sides will rotate, the rotation of the connecting blocks 508 will in turn drive the sliding blocks 502 to slide towards each other on the upper end of the bottom plate 501, the sliding will be stable outside the second fixed rod 509, and will synchronously drive the clamping plates 503 on the opposite side to move, finally making the clamping plates 503 clamp the workpiece, thereby realizing the fixation of the workpiece and achieving the purpose of center positioning of the workpiece. When encountering workpieces of asymmetric shape or special size, the clamping plates 503 can be moved by rotating the screw rod 505, at this time the first fixed rod 504 will slide inside the sliding block 502, making the movement of the clamping plates 503 stable, thereby realizing the fine adjustment of the position of the clamping plates 503. Through the two-way air cylinder 507, the connecting blocks 508, the sliding blocks 502 and the clamping plates 503, the workpiece can be positioned more accurately, especially for center positioning, which helps to improve the precision of subsequent processing, so that the clamping mechanism 5 can adapt to workpieces of different shapes, increasing the versatility of the clamping mechanism 5. Moreover, the entire operation process is relatively simple and does not require complex operation steps, which helps to improve work efficiency. When processing, the hydraulic cylinder 4 drives the processing knife 3 on its output end to move up and down, at the same time, the electric sliding rail 6 drives the workpiece clamped on the bottom plate 501 to move, thereby realizing the processing of the workpiece.

[0034] Working principle: when in use, first place the workpiece to be processed on the bottom plate 501, at this time the output end of the two-way air cylinder 507 extends, thereby driving the moving block 506 to slide inside the bottom plate 501, the sliding of the moving block 506 will drive the connecting blocks 508 on both sides to rotate, the rotation of the connecting blocks 508 will drive the sliding blocks 502 to move towards each other, thereby making the clamping plates 503 clamp the workpiece, realizing the fixation of the workpiece, thereby realizing the positioning of the center of the workpiece. When the workpiece is asymmetric, rotate the screw rod 505 to drive the clamping plates 503 to move, thereby adjusting the position of the clamping plates 503;

[0035] Second, when the upper end of the protective door 201 is observed through the window, the water beads are blocked from the observation line of sight, the motor 203 is started to drive the reciprocating screw rod 206 to rotate, so that the mounting plate 204 drives the fixed plate 205 to move, the movement of the fixed plate 205 will make the cleaning block 211 wipe the observation window on the protective door 201, so that the operator can observe, when the cleaning block 211 is replaced, the push rod 202 is pressed first, so that the push rod 202 drives the rotating block 209 to rotate, and then the clamping block 208 moves towards each other, the movement of the clamping block 208 will gradually release the clamping of the fixed plate 205, when the clamping block 208 is separated from the inside of the fixed plate 205, the fixed plate 205 can be slid from one side of the mounting plate 204, and the replacement of the cleaning block 211 is realized, which is convenient to operate.

[0036] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
